You are misinterpreting what’s going on. Universities are places where lots of people live and work. There’s support staff for all of that. Some activity that goes on is teaching. Some is research. Some is community engagement and outreach. All of those functions also need support staff, particularly research. At many large universities, research is the primary function, not teaching. Research requires a lot more support staff than teaching.

I think I am not misinterpreting. I expect an university to do teaching and focus on teaching (including some research). I expect any auxiliary activity to be minimized as much as possible, from cafeteria workers and campus electricians to HR and accounting.
